在试管中

For example, if an open test tube with some water in the bottom is placed in a room in which the air is relatively dry, water vapor will diffuse out through the column of air in the test tube.

例如，当一支底部有水的开口试管被放置在一间空气相对干燥的房间里，水蒸气就会通过试管中的空气柱散布出来。

Methods to place nux vomical curare fluid into plastic bottle and 4 groups test tubes made ofsmall fresh white rat skin,with group a and c being control groups,group b and d being ultrasonic group.contents of chinese medicine were test at different time and statistic analyzed and compared.

an approach divides the sonoluminescence from the sound field by using test tube with black plastics and the isotropic light trap is applied to collect sonoluminescence in the trough which irradiates hematoporphyrin out of the sound field.the results of our work suggest that ultrasonically induced cavitation produces nonequilibrium high temperature, emits shock waves, together with the cavitation energy in hematoporphyrin solution activating hematoporphyrin.

从超声空化产生的声致荧光出发，采用试管外包裹黑色塑料的方法将大量生理盐水的声致发光与其余能量形式分开，在相同条件下，使用集光球收集水槽中盐水的声致荧光，将荧光引出声场单独作用血卟啉。结果表明，水槽中盐水的空化热能、冲击波与试管中血卟啉溶液空化产生的高温、高压、冲击波等多种能量的合作用激活血卟啉。

It turned out reproduction rete of chrysanthemum was raised,the regular,non-plant diseases and insect pests could be offered to the market. Shoot tip were used as explants to study the effects of different sterilization methods, illumination intensity and concentrations of 6-BA and NAA on shoot propagation. Rooting with perlite, vermiculite and river sand instead of agar was studied. In the process of preliminary multiplication, the effect of using 0.1% HgCl_2 in sterilization of explants was better than using saturated bleaching solution. The highest multiplication rate was found under whole illumination. MS media with 6-BA from 0.2 mg·L~(-1) to 5 mg·L~(-1) and NAA from 0.05 mg·L~(-1) to 2 mg·L~(-1) were tested and as a result, the highest differentiation rate and the multiplication rate was reached with 0.2 mg·L~(-1) 6-BA, 0.05 mg·L~(-1) NAA.

本实验以菊花的茎尖为外植体，研究了不同灭菌方法，光照强度，全光照、半光照和弱光处理以及不同6-BA和NAA浓度及配比对于试管苗增殖的影响，并研究了珍珠岩、蛭石和河砂等琼脂替代物对于菊花生根的影响，结果表明：在初代培养物建立的过程中采用0.1％升汞进行表面灭菌的效果好于饱和漂白粉的灭菌效果；在全光照条件下外植体的增殖倍数最高；在试管苗增殖培养的过程中，以MS为基本培养基，并在培养基中添加0.2～5mg·L~(-1)6-BA和0.05～2mg·L~(-1)NAA，其中0.2mg·L~(-1)6-BA和0.05mg·L~(-1)NAA最适于外植体的分化和增殖，其分化率为100％，增殖倍数为12。

From tube A, pipet 1 mL of its contents into the one remaining tube not included in a set, and mix.

从试管A中，移取1mL其内容物至剩下的一个没有包括在任何一组中的试管中，并混匀。

In a pitot-tube, a small filament of the fluid is brought to rest in a small-bore tube, the impact pressure being measured against the static pressure of the fluid in an outer tube.

在皮托管里，一丝液体被注入一个小口径的试管中，其冲击压力是通过另一根试管里的液体的静态压力测得的。

By teaching material medium operation method has a test, be in 3 tube of amylase solution and 3 tube of amylaceous solution in boiling water in the meantime heat preservation 5min, the amylaceous solution that leaves this temperature again and amylase solution mix equably continue heat preservation 5min.

按教材中的操作方法进行试验，把装有淀粉酶溶液的3号试管和装有淀粉溶液的3号试管在沸水中同时保温5min，再把此温度下的淀粉溶液和淀粉酶溶液均匀混合继续保温5min。

The study was done in test tubes, but there's no need to wait for confirmation — bring on the guacamole!

这项研究是在试管中进行的，但是，不必等待其确认，食用色拉调味酱即可。

Place 5 ml in a test-tube immersed in iced water, add 0.4 ml of a 100 g/l solution of potassium chloride R, 0.1 ml of diphenylamine solution R and, dropwise with shaking, 5 ml of nitrogen-free sulphuric acid R.

硝酸盐：取本品5ml置试管中，于冰浴中冷却，加100g/l氯化钾溶液0.4ml与0.1%二苯胺溶液0.1ml，边摇边滴加无氮的硫酸5ml，摇匀，将试管于50℃水浴中放置15分钟，溶液产生的蓝色与标准硝酸盐溶液(2 ppm NO3)0.5ml，加无硝酸盐的水4.5ml，在同一时间用同一方法处理后的颜色比较，不得更深。

Then the scales are taken off the steel samples in an argon cabinet and are immediately put into a test tube filled with argon. Part of the rust scale is then transferred into a sample box made of organic glass sealed leakproof and is ready for Mossbauer spectrum analysis.
